Thaulos

Thaulos (466 BC-431 BC) was an Athenian naval captain during the Peloponnesian War. In 431 BC, during the Siege of Megaris, he led a three-ship naval blockade of the Spartan siege force at Megaris, but he was killed when the Spartan mercenary Kassandra and her ship Adrestia broke through the blockade and sunk the Athenian ships.
